Frequently Asked
What should I blend this with?
This is our blank slate protein flavor. So you can add in any fruit, add in cacao powder, and make it as sweet (or not-so-sweet) as you’d prefer. If the number of options is paralyzing, we’d say start with frozen strawberries, frozen banana, and milk!
Can I bake with this protein powder?
Absolutely. We love adding it to brownies and chocolate muffins.
Is this tested for toxins?
Yes, every batch is tested in 3rd party labs for heavy metals, mycotoxins, mold, yeast and pesticides.
Does this have whey in it?
No whey! Just plant-based organic protein blend.

How many mushrooms can I take in a day? Can I combine mushrooms?
We strongly encourage you to work with a qualified health care professional whenever making changes to your supplementation protocol, and especially if you’re someone with specific health-related needs or concerns. When you are totally new to consuming our products or functional mushrooms and adaptogens in general, we suggest that you start with one serving per day. Every Four Sigmatic product contains a potent dose of functional ingredients with a minimum of 500 mg/serving. After a few days, you can start building your routine with up to 3-4 servings per day. The functional mushrooms and adaptogens we use are safe to take long-term but the amount needed daily is slightly different for everyone. Feel free to pair products together to increase flavor or benefits. Mixing and matching is encouraged! Always listen to your body and increase or decrease dosage as you see fit.Functional foods are one part of a balanced wellness routine. Don’t forget to continue to address the other aspects of your wellbeing like sleep, movement, and mental health! True wellbeing takes time. Be gentle with yourself, go slow, always listen to your body, and support your foundation from many angles like healthy eating, better-for-you habits, exercise, and supporting your mental health in ways that feel best for you.
Where do you source the mushrooms?
Our top priorities are to offer functional mushrooms as nature intended, in the way they’ve been used for hundreds (some, even thousands) of years in cultures around the world, and that have been scientifically proven. This trifecta means using real mushrooms. Let us explain. The mushroom marketplace is currently flooded with products that don’t actually contain mushrooms. Instead, they are almost all mycelium (essentially mushroom roots system), grown on grains like rice and oats, without any of the actual mushroom. This grain is not separated from the mycelium so you are getting mostly grain, with some mycelium. Almost all US Grown “mushrooms follow this method which is not only incredibly misleading, it is also not how nature intended, far from the way cultures have used mushrooms for thousands of years, and scientifically proven to be far less beneficial than the real mushrooms. We aim to educate our consumers on what is truly important to look for when using functional mushrooms. Using real mushrooms is at the very top of our list. Even though this method is 5-10x more expensive, time-consuming, and means we choose to not source for the US, we are committed to offering the best, most nutrient-dense, clean, quality, and powerful ingredients possible. We use the real mushrooms, also known as fruiting bodies, of Reishi, Lion's Mane, Cordyceps, Shiitake, Turkey Tail, Tremella, and Maitake grown and cultivated on an amazing organic family farm in China. We’ve been working with these farmers for over 7 years and visit regularly to ensure the practices are aligned with our values as a brand. The decision to source from China was made very mindfully and for several reasons: China has the longest history of mushroom cultivation on the planet. They’ve been growing these specific species of functional mushrooms for over a thousand years—all the way back to 600 AD! China is THE leading producer of functional mushrooms and the only place you can purchase organic, log-grown, extracted real mushroom fruiting bodies. The organic family farm we’ve partnered with prides itself on optimizing the growing medium for each specific mushroom, so they grow exactly like they would in nature. For example, the red Reishi fruiting body is grown on basswood logs that are buried underground. Additionally, our Chaga mushrooms are sustainably wild-harvested. The Finnish favorite and King of Mushrooms, Chaga, grows on Birch trees, so we source ours from organic land on the largest Birch forest in the world, the Taiga, located in Siberia. Only part of the Chaga conk is removed to ensure it will continue to grow without harming the tree! All of our mushrooms are extracted to provide the highest amount of beta-glucans and polysaccharides, as well as triterpenes and other more adaptogenic compounds. Triterpenes, which give the mushrooms their increased adaptogenic properties, are poorly soluble in water. To fully extract all of the compounds from the terpenes, the extraction takes the process one step further by using alcohol to extract. Our main focus is to offer you the safest, cleanest, and highest-quality products possible. To ensure this, once the mushrooms are brought to our production facilities within the United States, every single batch of our products are tested in third-party laboratories for heavy metals, allergens, bad bacteria, yeasts, molds, mycotoxins, and pesticides before they get in your hands. This is very important to us, and we’ve been doing it since day 1. You can read even more about our quality standards here!
Do you offer samples?
While we're not able to send specific samples directly, we do offer a 100% money-back guarantee on all products! So if you do purchase a product through our website and you are unhappy with it, we are happy to issue a refund within 120 days of purchase. We also have multiple resellers where you can often purchase single packets of our products! Find a location near you here:
I have to take a drug test. Is it ok to consume this hemp protein?
While we cannot be certain about everything someone might be tested for, our products are 100% legal. None of our products are on the World Anti-Doping Agency’s (WADA’s) prohibited list, and they are legal all around the world. Most functional mushrooms and adaptogenic herbs have been used for over 5,000 years, so it is very unlikely that they will ever make the list or become illegal. Please be aware that our Organic Plant-based Proteins do contain hemp protein but each batch is tested for THC and levels are no more than 5 ppm.
What is the amino acid profile?
Unfortunately, we cannot currently share the amino acid profile of our protein powder. The reasons for this are because we’re not making claims for specific amino acids and the breakdown is currently proprietary to preserve our competitive stance with the product. We can assure you that our protein formulations take into consideration the Protein Digestibility Corrected Amino Acid Score or PDCAAS as it is known in the industry. Our protein is very high quality and the PDCAAS value is 0.83. PDCAAS is evaluated on a 0 to 1 scale, meaning the closer the value to 1, the higher the ability to digest the essential amino acids and greater ability to lose less of the protein quality to waste.
Where can I find the ingredients and nutritional breakdown for each of your products?
We list all of our ingredients and detailed product information on each product page. For example, this is our product detail page for our Think Organic Coffee, Ground. The nutritional labels can always be found in the images section at the top of the page (just click over a few photos) and our ingredient breakdown can be found by scrolling down the page just a bit.
Could I have an allergic reaction?
ndividual allergic reactions are always possible when consuming something new. If you have any concerns, please consult your healthcare practitioner to develop a plan on how you can integrate functional mushrooms into your diet.
Do you use fruiting body or mycelium in your products?
The functional mushroom marketplace sometimes feels like the wild, wild West. The majority of products sold as “mushrooms” are actually not mushrooms at all, they are instead mycelium (essentially, the mushroom root system) grown on grain. At Four Sigmatic, we aim to bring the best of nature to fit your daily routine. This means offering ingredients in the way nature intended! When it comes to mushrooms, that means using the real mushroom or fruiting body. Let us break it down a little further: All cultures, traditions, and animals have always consumed the fruiting body or real mushroom exclusively. We believe in the ancient tradition of fruiting bodies of mushrooms, that humans have been using for literally thousands of years. The research on mycelium is still emerging, but existing research has shown that fruiting bodies have 15 TIMES more active ingredients than mycelium. (By active ingredients we mean beta-glucans, triterpenes, ergosterol, ergothioneine, etc.) The majority of mycelium-based products in America are in fact, not pure mycelium but myceliated grain where the mycelium is grown on a grain substrate, and this grain ends up being a significant portion of the final product. Fun fact: if you use mycelium you can’t even call it a “Mushroom” according to the FDA! We serve up mushrooms as they’ve been used since ancient times, in a way that helps everyone to meet the demands of modern life. Using the fruiting body is incredibly more expensive, time-consuming, difficult to make tasty (it is really bitter in its pure extracted form!), but we want to offer you real mushrooms—extracted fruiting bodies—that have the research and tradition standing behind them.
What is the shelf life of your products?
The shelf life of our products are between 1-3 years depending on the product! The individual packets do last longer than the bulk products since the larger containers will be re-opened each time they are used. All of our products will have a specific expiration date on the packaging for your reference as well.
Are these sweetened/unsweetened?
Our organic proteins, depending on flavor, are sweetened with either monk fruit, lucuma, coconut palm sugar, yacon juice powder, or maple syrup powder.
Are these canisters filed to the top?
No - but for a reason! We fill all of our products by weight not volume, so your canisters will not be filled to the top with powder. Because these products contain a powder, it may appear less to the eye because of the potential for the powder to condense during transit but rest assured that the package does include the actual number of servings! To help ensure that you receive each of those precious servings, we've included a scoop in each canister for measuring. If you don't see this scoop at the top of the canister, just shake down the contents a bit in case it's settled into your product during transit :)
Can athletes use Four Sigmatic protein?
We do use hemp in our protein blend. If that is allowed for your sport, you are good!
Can I mix with other products of yours?
ou absolutely can - we love product stacking to get those extra mushrooms and adaptogens in! Our new favorite way is to add a scoop of our organic protein to our Think Organic Coffee for a high protein coffee to start the day!
What is the recommend storage instructions?
A dry and cool place.
How well do your organic proteins mix with liquids?
From what our reviews say, pretty great! Just shake with ice in a shaker for a smooth texture and delicious flavor.
How many grams of protein does the Unflavored Organic Protein contain per serving?
18 grams of organic plant-based protein.
Can Four Sigmatic Unflavored Protein be used as a meal replacement?
Technically no based on having less calories than what is regulated as a meal. We recommend adding in fruit and dairy for a more full smoothie if you are looking to replace a meal.
